|The Automatic Choice For Spectroscopy, Chromatography and Electrophoresis
PeakFit Automatically Places Peaks in Three Ways
PeakFit uses three procedures to automatically place hidden peaks;
while each is a strong solution, one method may work better with some
data sets than others.
The Residuals procedure initially places peaks by finding local
maxima in a smoothed data stream. Hidden peaks are then optionally added
where peaks in the residuals occur.
The Second Derivative procedure searches for local minima within a
smoothed second derivative data stream. These local minima often reveal
The Deconvolution procedure uses a Gaussian response function with a
Fourier deconvolution / filtering algorithm. A successfully deconvolved
spectrum will consist of “sharpened” peaks of equivalent area. The goal
is to enhance the hidden peaks so that each represents a local maximum.
